Ninja Nipples 

What a woman has if she goes all day without a bra on and no one noticed.

We were out all day with Jane and never noticed she wasn't wearing a bra. It was nipply out and she wasn't wearing a jacket either. The woman's got ninja nipples!

panty ninja 

A guy who is able to stealthily infiltrate, using charm or bravado, almost any female's defense barrier, namely whatever pantywear is "defending" her lower territories.

Greg: Yo, Eric, can you believe TJ hit that blonde chick's gash last night?
Eric: Shit, man, TJ's a freakin' panty ninja.

Although Meegan was really a cum dumpster, she often acted demure so guys would feel like panty ninjas when she finally pulled down her drawers.

loot ninja 

An mmorpg term referring to a devious being who takes phat l00t that is not rightfully his. They often try to cover up their evil ways by blaming their non existent little brother.

Angry party member: Hey you stole my phat l00t!

Loot ninja: I'm sorry my little brother was playing! It's not my fault!
